I'll put my little piece in here since everyone's doing it.

I've mined with Yiimp's DGB Skein algo, and at full TDP, stock settings I get averaged 1057Mh/s, If I undervolted the card to about 44% TDP(124W) I'd average 850-920Mh/s with -504 on the memory and +150 on the core.

The card I'm using is the EVGA FTW3 GTX 1080 Ti as seen here - http://i.imgur.com/4Hehs2Y.jpg

I've decided that mining skein wasn't profitable for me so I'm mainly mining ZClassic, ZCash, and GroestlCoin.(Averaging $10-$15 per day depending on coin value)
